"Physicist and mathematician Prof. Frank J. Tipler is not only a credible physicist, but indeed the most credible physicist to date. All other physicists either apply the known laws of physics to narrowly-confined inquiries (i.e., more narrow than the range of applicability of said physical laws), or outright reject the known physical laws if they conflict with their distaste for religion."
If they (atheists) want a war, I intend to win it...
Prof. Tipler's Ph.D. is in the field of Global General Relativity, which is the field created by Profs. Stephen Hawking and Roger Penrose during the formulation of their Singularity Theorems in the 1960s. Global General Relativity is General Relativity applied on the scale of the entire universe as a whole, and is the most elite and rarefied field of physics. Tipler is also an expert in quantum field theory (i.e., Quantum Mechanics combined with special-relativistic particle physics) and computer theory.
What you can show using physics, forces this universe to continue to exist. As long as you're using general relativity and quantum mechanics you are forced to conclude that God exists.
Prof. Tipler's Omega Point cosmology, which is a proof of God's existence, is a mathematical theorem per the known laws of physics (viz., the Second Law of Thermodynamics, General Relativity, and Quantum Mechanics), of which have been confirmed by every experiment to date. Hence, the only way to avoid the Omega Point Theorem is to reject empirical science. As Prof. Hawking wrote, "one cannot really argue with a mathematical theorem." (From p. 67 of Stephen Hawking, The Illustrated A Brief History of Time [New York, NY: Bantam Books, 1996; 1st ed., 1988].) Tipler's Omega Point cosmology has been published and extensively peer-reviewed in leading physics journals.
A scientist... must accept the results of experiment, and nothing but the results of experiment.
"The Many Worlds Interpretation of Quantum Mechanics is trivially true..."
